Working Theory

Whether you are looking for improved mid-end torque, better vigor or you just want to blow everybody off the line, this Chevrolet Astro Van performance chip is your choice. O2 sensor performance chip results salient changes in horsepower at the wheels. installation is easy, no special tools or expertise required. Faster take off, more power, torque, better throttle response and improved fuel consumption. Gain 10% more horsepower, 10% torque and get awesome speeding up. Magnum O2 chip has dyno-bench-tested results for producing more performance level for Chevrolet Astro Van. This chip takes off the restrictions employed by the Powertrain Control Module on the fuel maps. By tricking exhaust air fuel sensor signal, Chevrolet Astro Van O2 Sensor Chip gives increased pony and salient torque throughout the RPM range without compromise of economy.

You do not need to dismount and solder your Chevrolet Astro Van’s Engine computer since the signal of O2 sensor fuel management chip overwrites the Electronic Control Module resulting in higher performance capability, low-range torque as well as improved pep. Enjoy the advantages of an aggressive engine, without annoying flat spots. Detailed instructions, perfect fit. No service engine soon light issue. This performance chip is vehicle specific according to the type and operating range of factory O2 sensor. O2 sensor performance chip does not work together with performance tuners or any tuned-up / decatted exhaust which trips the warning light.

Packing List

1 x Oxygen Sensor Performance Chip

4 x Bullet Connector

1 x Hose clamp

2 x Zip Tie

4 x Heat Shrink Tubing

1 x Installation Instructions

Injected gasoline engines controlled by Electronic Control Unit have an oxygen sensor to measure the amount of oxygen contained in the exhaust gas. These sensors deliver to the ECU fluctuating voltages according to the actual oxygen consistence of the air fuel mixture. Oxygen sensors are used to reduce vehicle emissions, by ensuring that engines burn their fuel efficiently and cleanly. In modern vehicles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline lead into the engine is rich (too much fuel) or lean (too little fuel). Regarding engine performance factory economy- and emission oriented AFR is proved to be "lean". If we fool the oxygen sensor signal delivered the ECU we may effectively boost engine horsepower. Magnum Performance Oxygen Sensor chip is designed to fool fluctuating O2 sensor signal in order to modify the air fuel ratio. Integrated voltage range-monitor is incorporated to avoid "signal out of range" or "voltage below threshold" trouble codes. Dual exhaust with two post oxygen sensors requires 2 units. To avoid misconceptions, Magnum Oxygen Sensor Performance Chip is not resistor. Oxygen sensor voltage signal cannot be tweaked with a resistor.

If more than one oxygen sensor fitted, chip plugs into the downstream oxygen sensor.

If more than one oxygen sensor fitted, chip plugs into the downstream oxygen sensor.

Dual exhaust with two post oxygen sensors requires 2 units.

Prior to setup make sure the oxygen sensor works flawless in full range. Slow or worn oxygen sensor may cause the chip work inefficiently with zero to minimum gains.

Claims correlate to factory condition engine. Defect or extensive wear and tear of related parts or systems as oxygen sensor, sparkplug, fuel filter, injectors, injection or ignition system can result in no or minimum effect. Please get the vehicle checked by a certified mechanic prior to installation to avoid undesired inefficiency.

This performance chip does not work in conjunction with any upgrade affects the fuel trim or triggers the check engine light.

notable acceleration boost

though no MIL light i was worried of, notable acceleration boost but the chip delivered less power than expected and i am on the fence it improved fuel milage or car avereges the same in mles per gallon

Install is absolutely worry free

i needed two chips due to true (removed) dual exhaust, they seem to work fine and thus far no MIL that i was afraid of. Super fast free shipping and unequivocally tech team made efforts to address their input to your specific needs. They are as persistant as skilled. Install is absolutely worry free. I'll recommend this chip to tow truck fellows without hesitation.

performance changes are noticeable

The chip was shipped out quick. It was also the best price that i found anywhere on the internet, and at local shops in town. I have had a good shopping experience buying from magnum, I have also purchased some performance intakes for my Tundra and had no problem waiting for those either. The chip does what it was claimed to however check engine light popped up on the other day. I contacted technical support and I was told this is normal once my exhaust is decatted. Now I contemplate to reinstall a cheap cat to check what's under the sun. The performance changes are noticeable but as far as I know horsepower cannot be maxed out until MIL light is turned on. There is a restriction of some sort implied by the computer. I have to knock off one star for that side effect. Will revise my review if MIL is gone.

No horsepower change at all

I bought this chip for my truck to try to squeeze a little more pep and more mileage out the truck. Installed fine, no problems. No horsepower change at all. Stock my mileage was and is again 18 miles per gallon. Tried to gas up with higher octane fuel, getting same result economy and performance wise. I was really looking to squeeze more power out the old girl, since I use it for work. I wouldn't recommend it. Techs seemed to be prudent when supporting my issue but it still has not been solved.

product works and does what it is claimed t

I was under the false assumption that e-commerce companies conduct their job along the lines of business interest. I got my gas saver module in a few days and faced trouble when I went to install it. Contacted tech team and reply was instantaneous bearing resemblance to professionals. Undescribably unparalleled communication, extremely helpful tech's. No qualms, product works and does what it is claimed to. I will recommend this product to everyone and I'm about to sign up as a reseller.

this miniature chip has done what it said

i have an Suburban 5.7L that doesn't get the best fuel mileage and was a bit sluggish uphill. so over the year i find new ways to get better fuel mileage and this miniature chip has done what it said. plus if you want more power oxygen sensor performance chip will do the trick.

gives you a noticeable amount of horsepower and torque

I have been disbeliever ever since I bought a resistor chip that fried my mass air flow sensor. This chips is amazing though. It actually gives you a noticeable amount of horsepower and torque. I recommend this product to anyone looking to get the power they want out of their truck.
